2023-01-31accel: fix CONFIG_DRM dependenciesArnd Bergmann
At the moment, accel drivers can be built-in even with CONFIG_DRM=m, but this causes a link failure: x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_dev_init': ivpu_drv.c:(.text+0x1535): undefined reference to `drmm_kmalloc' x86_64-linux-ld: ivpu_drv.c:(.text+0x1562): undefined reference to `drmm_kmalloc' x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_remove': ivpu_drv.c:(.text+0x1faa): undefined reference to `drm_dev_unregister' x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_probe': ivpu_drv.c:(.text+0x1fef): undefined reference to `__devm_drm_dev_alloc' The problem is that DRM_ACCEL is a 'bool' symbol, so driver that only depend on DRM_ACCEL but not also on DRM do not see the restriction to =m configs. To ensure that each accel driver has an implied dependency on CONFIG_DRM, enclose the entire Kconfig file in an if/endif check.

2023-01-30drm/shmem: Cleanup drm_gem_shmem_create_with_handle()Rob Clark
Once we create the handle, the handle owns the reference. Currently nothing was doing anything with the shmem ptr after the handle was created, but let's change drm_gem_shmem_create_with_handle() to not return the pointer, so-as to not encourage problematic use of this function in the future. As a bonus, it makes the code a bit cleaner.

2023-01-26drm/probe_helper: sort out poll_running vs poll_enabledDmitry Baryshkov
There are two flags attemting to guard connector polling: poll_enabled and poll_running. While poll_enabled semantics is clearly defined and fully adhered (mark that drm_kms_helper_poll_init() was called and not finalized by the _fini() call), the poll_running flag doesn't have such clearliness. This flag is used only in drm_helper_probe_single_connector_modes() to guard calling of drm_kms_helper_poll_enable, it doesn't guard the drm_kms_helper_poll_fini(), etc. Change it to only be set if the polling is actually running. Tie HPD enablement to this flag. This fixes the following warning reported after merging the HPD series: Hot plug detection already enabled WARNING: CPU: 2 PID: 9 at drivers/gpu/drm/drm_bridge.c:1257 drm_bridge_hpd_enable+0x94/0x9c [drm] Modules linked in: videobuf2_memops snd_soc_simple_card snd_soc_simple_card_utils fsl_imx8_ddr_perf videobuf2_common snd_soc_imx_spdif adv7511 etnaviv imx8m_ddrc imx_dcss mc cec nwl_dsi gov CPU: 2 PID: 9 Comm: kworker/u8:0 Not tainted 6.2.0-rc2-15208-g25b283acd578 #6 Hardware name: NXP i.MX8MQ EVK (DT) Workqueue: events_unbound deferred_probe_work_func pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : drm_bridge_hpd_enable+0x94/0x9c [drm] lr : drm_bridge_hpd_enable+0x94/0x9c [drm] sp : ffff800009ef3740 x29: ffff800009ef3740 x28: ffff000009331f00 x27: 0000000000001000 x26: 0000000000000020 x25: ffff800001148ed8 x24: ffff00000a8fe000 x23: 00000000fffffffd x22: ffff000005086348 x21: ffff800001133ee0 x20: ffff00000550d800 x19: ffff000005086288 x18: 0000000000000006 x17: 0000000000000000 x16: ffff8000096ef008 x15: 97ffff2891004260 x14: 2a1403e194000000 x13: 97ffff2891004260 x12: 2a1403e194000000 x11: 7100385f29400801 x10: 0000000000000aa0 x9 : ffff800008112744 x8 : ffff000000250b00 x7 : 0000000000000003 x6 : 0000000000000011 x5 : 0000000000000000 x4 : ffff0000bd986a48 x3 : 0000000000000001 x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff000000250000 Call trace: drm_bridge_hpd_enable+0x94/0x9c [drm] drm_bridge_connector_enable_hpd+0x2c/0x3c [drm_kms_helper] drm_kms_helper_poll_enable+0x94/0x10c [drm_kms_helper] drm_helper_probe_single_connector_modes+0x1a8/0x510 [drm_kms_helper] drm_client_modeset_probe+0x204/0x1190 [drm] __drm_fb_helper_initial_config_and_unlock+0x5c/0x4a4 [drm_kms_helper] drm_fb_helper_initial_config+0x54/0x6c [drm_kms_helper] drm_fbdev_client_hotplug+0xd0/0x140 [drm_kms_helper] drm_fbdev_generic_setup+0x90/0x154 [drm_kms_helper] dcss_kms_attach+0x1c8/0x254 [imx_dcss] dcss_drv_platform_probe+0x90/0xfc [imx_dcss] platform_probe+0x70/0xcc really_probe+0xc4/0x2e0 __driver_probe_device+0x80/0xf0 driver_probe_device+0xe0/0x164 __device_attach_driver+0xc0/0x13c bus_for_each_drv+0x84/0xe0 __device_attach+0xa4/0x1a0 device_initial_probe+0x1c/0x30 bus_probe_device+0xa4/0xb0 deferred_probe_work_func+0x90/0xd0 process_one_work+0x200/0x474 worker_thread+0x74/0x43c kthread+0xfc/0x110 ret_from_fork+0x10/0x20 ---[ end trace 0000000000000000 ]--- Reported-by: Laurentiu Palcu <laurentiu.palcu@oss.nxp.com> Fixes: c8268795c9a9 ("drm/probe-helper: enable and disable HPD on connectors") Tested-by: Marek Szyprowski <m.szyprowski@samsung.com> Tested-by: Chen-Yu Tsai <wenst@chromium.org> Acked-by: Laurentiu Palcu <laurentiu.palcu@oss.nxp.com> Tested-by: Laurentiu Palcu <laurentiu.palcu@oss.nxp.com> Tested-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230124104548.3234554-2-dmitry.baryshkov@linaro.org

For uninitialized framebuffers, only release the DRM client and free the fbdev memory. Do not attempt to clean up the framebuffer. DRM fbdev clients have a two-step initialization: first create the DRM client; then create the framebuffer device on the first successful hotplug event.

2023-01-25drm/nouveau/devinit: Convert function disable() to be voidDeepak R Varma
The current design of callback function disable() of struct nvkm_devinit_func is defined to return a u64 value. In its implementation in the driver modules, the function always returns a fixed value 0. Hence the design and implementation of this function should be enhanced to return void instead of a fixed value. This change also eliminates untouched return variables. The change is identified using the returnvar.cocci Coccinelle semantic patch script.
